Warner Bros. Games and developer NetherRealm Studios have announced that Mortal Kombat 1 is unleashing Khaos this September when the Khaos Reigns expansion will be released for the game.

The expansion includes two aspects, one is a story expansion and the second is an all-new Kombat Pack. Here is what we know for the new story expansion, Khaos Reigns

After repelling the invaders who endangered Fire God Liu Kang’s New Era of peace, Mortal Kombat 1 “Khaos Reigns” expands the story campaign with an all-new cinematic narrative. When a perilous threat arrives from an alternate timeline, led by the ruthless Titan Havik whose sole mission is to throw the realms into khaos, Liu Kang must rally his champions and put faith in his enemies to defeat this grave danger. If they fail, the New Era will be reduced to anarchy.

For Kombat Pack 2, there are six new characters being added to the game, three of them will arrive the same day as the expansion, while the remaining three will release over time. This is the list of fighters included in the pass, the first three are tied to the story expansion:

• Noob Saibot voiced by Kaiji Tang

• Cyrax voiced by Enuka Okuma

• Sektor voiced by Erika Ishii

• Ghostface voiced by Roger L. Jackson

• Conan the Barbarian featuring the likeness of actor Arnold Schwarzenegger.

• T-1000 featuring the voice and likeness of actor Robert Patrick

Finally, in addition to new story and kombatants, the Animalities are also returning to the game. These Animalities, are fan-favourite finishing moves and will be returning as a free content update for all Mortal Kombat 1 owners. Allowing characters to morph into their spirit animal to annihilate defeated opponents, Animalities can be performed by all playable fighters and will be available in conjunction with the Mortal Kombat 1: Khaos Reigns release.

The expansion and the free content will arrive on September 24 for PlayStation 5, Xbox Series X|S, PC and Switch.

Finally, we do have a trailer, but as its a Mortal Kombat trailer, it is age gated, so you need to watch it on YouTube.
